esphome VS connectedhomeip

For the ESP32, an hero is in the process of adding LVGL to ESPHome. You can try it out now: https://github.com/esphome/esphome/pull/6363

Here's the (very good!) preview documentation: https://deploy-preview-3678--esphome.netlify.app/components/...

This is such a game-changer for me that I'll be using the ESP32 over the ESP8266 for any projects involving displays from now on.

Solid state relay is probably a bad idea with all the extra heat-sinking, extra cost, and chance of getting counterfeits.

I do this with ESPHome & a J115F21C12VDCS.9 relay (note only the NO side is rated for 40A resistive): https://i.imgur.com/MqqOkoY.png

Choose any of the temperature sensors here for air temperature sensing: https://esphome.io/

Configuration is so easy. For the sensor, just copy the config from here, for example: https://esphome.io/components/sensor/bme280. Add a gpio output (https://esphome.io/components/output/gpio) and a bang-bang climate controller (https://esphome.io/components/climate/bang_bang.html)

You might want to take a look at https://esphome.io/ for an easy integration of an ESP32/8266 into home Assistant.

You can do this with a $30 Sonoff S31 running ESPHome [0]. Since the Sonoff wall switch can run a ping sensor against your server you could create a watchdog automation right on the S31 to shut off the mains power to the S31 switch and turn back on after X seconds.

There are other ways you could have the S31 do operational checks but ultimately ESPHome is probably an interesting consideration and supported by tons of off the shelf hardware.

They're pretty great and compatible with most things. ESPHome [1] is a great resource for getting ESP32's working nicely with HA and you can find lots of projects using it to learn from.

You'll likely need to do soldering if you want to connect sensors, batteries and the like.

Personally I really like what SEEED Studio [2] does with their ESP32 boards and they have nice docs.

Maybe you could set up ESPHome on the ESP32. It might make connecting those components easier, plus a decent web server built in. Then your app can be set up to access data provided by the ESPHome web server.

# # Setting pins for sda and scl will be required until https://github.com/esphome/esphome/pull/2970 is released

Probably an unpopular opinion, but for the simple stuff you may just want to use something like EspHome where you just need to create a yaml file. Once you’re comfortable with that maybe get into something a bit more advanced, but esphome make it a breeze. It integrates with home assistant if you already have that in place as well.

ESPHome

They do have example Matter projects for the ESP32-C3/S3. I assume it's over WiFi and not thread.

IoT is a big space right now if you look at the companies who commit to https://github.com/project-chip/connectedhomeip. They come together at the CSA Member Meeting.

I followed this doc: https://github.com/project-chip/connectedhomeip/blob/master/docs/guides/esp32/setup_idf_chip.md

From https://github.com/project-chip/connectedhomeip#architecture... :

> Matter aims to build a universal IPv6-based communication protocol for smart home devices. The protocol defines the application layer that will be deployed on devices and the different link layers to help maintain interoperability. The following diagram illustrates the normal operational mode of the stack:

> [...] It is built with market-proven technologies using Internet Protocol (IP) and is compatible with Thread and Wi-Fi network transports.

> Matter was developed by a Working Group within the Connectivity Standards Alliance (Alliance). This Working Group develops and promotes the adoption of the Matter standard, a royalty-free connectivity standard to increase compatibility among smart home products, with security as a fundamental design tenet. The vision that led major industry players to come together to build Matter is that smart connectivity should be simple, reliable, and interoperable.

> [...] The code examples show simple interactions, and are supported on multiple transports -- Wi-Fi and Thread -- starting with resource-constrained (i.e., memory, processing) silicon platforms to help ensure Matter’s scalability.

Is there already a good (security) comparison of e.g. http basic auth, x10, ZigBee, mqtt, matter?

Bloaty is a nice tool.

When I worked on Matter a couple years ago, we had the problem that its backend http://www.capstone-engine.org/ did not support Xtensa, and produced some Python tools that could take output from bloaty or similar data from readelf or elftools, and produce several kinds of report.

My two cents from someone who has dealt with product name changes. Most recently I worked on the Chip repo which is now known as Matter. There are numerous references in the repo to chip despite the name change. See https://github.com/project-chip/connectedhomeip

Not sure if I'm asking in the right place so I apologise ahead. I'm trying to get one of the example projects from Matter onto my esp32 (ESP-WROOM-32) using espresiff. I am doing this on my raspberry pi btw. The problem I'm having now is that it get's stuck when I'm building (idf.py build command). It's always around 800/1135 and it doesn't go past it. The one where it is currently stuck is: [804/1135] Building C object esp-idf/bt/CMakeFiles/__idf_bt.dir/host/nimble/nimble/nimble/host/src/ble_gatts_lcl.c.obj.

I checked out v1.0.0 of the Matter repo and ran

I'm trying to build basic examples (light device for ESP32, Python controller for Raspberry Pi) following the guides on the official repository (https://github.com/project-chip/connectedhomeip). After solving some build errors, I managed to flash the ESP32 and run the controller on the RPi. However, I couldn't manage to commission the ESP32 from the RPi, because I kept getting a weird "mDNS: Timeout" error. Did anyone here have success with it? What am I missing?
